BPP

Bits Per Pixel is almost the same as a bitdepth. But BPP is only the RGB component. It tells us how many colors are used in the RGB part of the image. For example, 16BPP = 216 = 2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2 = 65536 colors. The term bitdepth is more commonly used to denote what a game or application needs to function properly, which is the number of colors plus other channels like alpha. For example, if you say there is a 32bit bitdepth, this doesn't mean 232 colors. Instead, this means a 24bit RGB space + an 8bit alpha. To make things clearer, instead of the term bitdepth people are starting to use the term BPC, or Bits Per Channel.
